LZP2 is a very fast compressor, designed to reach the pareto frontier, defined by Matt Mahoney as the fastest compressor for a given compression rate, as measured on his public benchmark "Large Text Compression Benchmark".

LZP2 is based on an optimized version of "Predictive LZ" algorithm, invented by Charles Bloom (and described here by Arturo Campos), which is very fast, but unfortunately has low hit-rate capabilities, and therefore offers little compression performance.The file i/o manager integrates a benchmark for your testing (lzp2 -bench).

4) MaximumCompression.com Only compression ratio is reported. No speed numbers.Unfortunately, LZP2 does not qualify for the MFC speed contest because it does not meet the minimal compression ratio rule (50%). arf, so long for the speed crown...
